A nurse is teaching a female adult client who has a new prescription for azathioprine to treat active rheumatoid arthritis. The nurse should inform the client about the need for which of the following diagnostic tests prior to starting the medication?
Bone density scan
Pregnancy test
Electrocardiogram
HbA1c
The Correct Answer is B
A. Bone density scan: Bone density scans assess for osteoporosis risk but are not required before starting azathioprine. They are unrelated to the medication’s safety profile.
B. Pregnancy test: Azathioprine can be teratogenic, posing risks to a developing fetus. A pregnancy test is essential before initiating therapy to ensure the client is not pregnant and to guide safe use of the medication.
C. Electrocardiogram: ECGs are used to assess cardiac function and detect arrhythmias. Azathioprine does not typically affect cardiac conduction, so this test is not required prior to therapy.
D. HbA1c: HbA1c measures long-term blood glucose control for diabetes management. It is not necessary for assessing safety before starting azathioprine for rheumatoid arthritis.

Correct Answer is D
Explanation
A. "TPN has a low risk of complications.": Total parenteral nutrition carries significant risks, including infection, metabolic imbalances, and liver dysfunction. It is not considered low risk.
B. "TPN will be administered through a peripheral IV in your arm.": TPN is typically administered through a central venous catheter because its high osmolarity can damage peripheral veins. Using a peripheral IV is not standard practice for long-term TPN.
C. "TPN may increase the risk of aspiration.": Aspiration risk is associated with enteral feeding through the gastrointestinal tract, not with TPN, which bypasses the digestive system entirely.
D. "TPN will provide nutrition without going through the digestive tract.": TPN delivers nutrients directly into the bloodstream, bypassing the gastrointestinal tract. This is an essential point for clients to understand regarding how TPN supports nutrition when oral or enteral feeding is not possible.
Correct Answer is ["1.5"]
Explanation
Calculation:
- Calculate the total dose in milligrams (mg).
Ordered dose: 0.02 mg/kg
Patient weight: 30 kg
Total dose (mg) = 0.02 mg/kg x 30 kg
= 0.6 mg.
- Calculate the volume to administer in milliliters (mL).
Total dose: 0.6 mg
Available concentration: 0.4 mg/mL
Volume (mL) = Total Dose (mg) / Available Concentration (mg/mL)
= 0.6 mg / 0.4 mg/mL
= 1.5 mL.
